The show may be edging towards the supernatural, but I don't see any indication at this point that the supernatural will be a primary component. Just a nice little frill - if that. I kept wondering, as David talked, if he was lying. He did have a motive, after all.
How are we supposed to be reacting to Burke's deception of Carolyn? I don't feel myself to be a good judge in this matter, because from what Carolyn said to Vicky - or was it to Roger? - I gather that, whatever our opinion may be of Burke, we're supposed to think he's handsome, and I don't think that.
Two weeks into this series, I have the same general thought as I had with the first episode: I wouldn't be watching this if it weren't for what comes later. It isn't the lack of the supernatural that's getting to me. More like a lack of humor that I can connect with, I think.
